president trump has repeated his threat to shut the us border with mexico unless congress agrees to fund his controversial plan to build a wall between the two countries. the dispute, prompted by illegal immigration, has caused the partial shutdown of the us government. a tourist bus in egypt has been hit by a roadside bomb, near the giza pyramids, killing three vietnamese tourists and a local guide. the authorities say 12 other people were injured. two of them are in a critical condition. the british home secretary has declared a "major incident" after a surge in the number of migrants trying to cross the english channel in small boats. 75 people have reached the uk in the past three days, and at least 221 people have attempted the crossing since the start of november. one of the most familiar names in british retailing, hmv, has confirmed that it's calling in the administrators. it's the second time in five years that hmv has hit serious financial

trouble, as our business correspondent rory cellan—jones reports. there's some flash photography coming up. from david bowie... ..to eltonjohn... ..to take that. they all chose the most famous name in high street music to launch an album. but that was then. now, hmv has collapsed into administration for the second time in five years. the main reason? people are finding other ways to get music and movies. netflix or spotify. i don't ever buy anything. no, i don't buy any. i download everything. i like movies but i'm not bothered about having them on dvd all the time and stuff like that. so it won't be that bad for me, to be honest. hmv‘s current owners bought it out of administration five years ago. but today they said an extremely

weak christmas and a poor outlook for music and dvd sales next year meant they couldn't go on trading. when it comes to physical sales, hmv is still a major force, with around a third of all music sales in the uk and about a quarter of the dvd and blu—ray market. but both are in decline and a big fall in recent months in sales of dvds seems to have pushed the firm over the edge. don't you get sick of it all? the rise of streaming services such as netflix and spotify means millions no longer choose to own dvds or cds, making the environment for a high street entertainment retailer ever harder. i don't think that's the whole story. i mean, obviously hmv have seen a change in terms of sales as people move to digital access models. but actually, i think what we're seeing now is something akin to some malaise on the high street generally with high rent and rates and a very torrid christmas trading period this year. i bought my first records in hmv. it was kind of like a magical place.

jimmy martin went on to work at hmv for 15 years and now helps run this store specialising in second—hand vinyl. he says there's still a place for music on the high street. i think it's all about making what is selling more desirable. i think there is a future for hmv. it's all second—hand product, the same way we do. i think there's a future for them to sort of diversifying and i think record shops can be as exciting as they were to me in 1985 when i first went into them. for now, the 125 stores remain open. the search is on for a buyer who believes that a business which has been through almost a century of change can still have a profitable future. rory cellan—jones, bbc news. now at this festive time of the year, it's time for a very special edition of click, filmed live before an audience who were treated to the very latest in technology, including augmented reality, drones and dancing robots. shush!

wire, hello there, little bedbugs. you are so sweet. i can change my face completely to match what i'm supposed to do. for example, i can bea supposed to do. for example, i can be a woman like this. it is a bit creepy. we have got an informal queueing system going on here, like pub. hello! 17 minutes to go until the show begins. and we are just writing the script. we should start with welcome. spencer kelly is really funny. better than some actors, anyway. technology has moved on quite a licence i was at school. we didn't have any computers then. you don't get nervous. he does, all the time! just getting in the last touches. are you looking forward to

it? yeah. welcome to click. from broadcasting house in london, this is bbc click live. please welcome the host, lara lewington and spencer kelly. —— your hosts. the host, lara lewington and spencer kelly. -- your hosts. good afternoon, london! welcome to click live. we are going to start with something truly magical. i would like you to put on your headsets and we will show the magic image. we are going to show you part of a show about gulliver ‘s travels. governor and his daughter gilly are in the land of the giants. they have in brought to the queen to entertain her. enjoy the show. why, hello there, little bedbugs. i hearyou

have repaired a special song for me? like we have a choice. your highness, iam like we have a choice. your highness, i am afraid there has been a small misunderstanding. you see, we do know how to play the piano, but we are not used to such a big one, you see. the peasant promiscuity play the piano for me. yes, but... and when promises are not kept it makes my heart so sad, and when my heart gets out i start crying, and when i start crying... please, don't cry. forget what i said. we will play a song, just as you were promised. 0k? said. we will play a song, just as you were promised. ok? you made. thanks. here we go. ready? ready. 0k. applause

.iam applause . i am going to call up one of the people behind this a r show from israel, please welcome sasha krindlen. thank you so much. can you explain what just happened 7 krindlen. thank you so much. can you explain whatjust happened? what we did is, we created the tools to incorporate ar into the live show. this tool allows the artist to focus not only on the stage but the entire venue as your canvas, not only on the stage but the entire venue as your canvas, if everybody turned their head while the scene was going on, there is a whole castle around you. and the second revolutionary part is the interaction part, because they have buttons on their headsets and they can interact with the live show and it gives a world of possibility. cool it gives a world of possibility. cool. part of the magic is going on in the glasses you are wearing. if you could put the glass is now, we are going to hear and see some more technology, because half the magic is going on in the goggles and the other half is going on in the gallery. backstage, which is where la ra gallery. backstage, which is where lara is right now. that's right.

throughout the whole of click live, lots of the technical stuff is happening back you. before the ar show you have just seen, isaac has been doing something here on a computer to make it happen. what have you been doing? what i am doing is controlling everything that happens in the ar, all the headsets, so happens in the ar, all the headsets, soi happens in the ar, all the headsets, so i can play god. i can make it rain on them, do things to the actors on stage, set the monitors so they can see what is going on. synchronise everything with the sound enlightening. please give it up sound enlightening. please give it upfor sound enlightening. please give it up for the ar show. so, we're just the robots ready. aj is getting his laser tag guns ready, it is he will trigger the robots to dance. —— because he will. in bristol, 30 robot toys are being taught to tango. well, sort of. to get the bots to bust a groove sunil

tony eastley, the all need to be set off at exact with the same time. —— simultaneously. so the team behind them had to get creative. so, this fires infrared. at all the robots. and the robots get the signal, and they know it is time to dance. 0k. now. atv a tv remote was just really boring, so we a tv remote was just really boring, so we got the laser gun. and it makes cool noises. it is cool, when it works. does it still need reloading? you have to reload the laser gun? and we can reset that. reloading? you have to reload the laser gun? and we can reset thatm isa laser gun? and we can reset thatm is a cone of light that comes out, not a single beam. if you get very close to our robotic is a net that is more narrow. further back you are, we find it is a better, wider ta ct. are, we find it is a better, wider tact. it is the same with the robots, they fire out a kind. they have used video animation software to choreograph the custom dance routine. i make one animation and

that will be distributed to all 30. the way that we did the mexican wave was that we put it into grid so that the last bit has an —— has a staggered animation, so far that bit, they all had their own little animation. so here i've got six animations. that is how you get this. this ripple effect. because the robots don't know where they are in relation to one another they have to be positioned in precisely the right place. but when it is done right... music plays. and i am joined here by their proud father, ceo and co—founder of reach robotics. thanks to having me. if

robotics can already do this for fun, there must be some exciting prospects about what they will be capable of soon. definitely. with mechamon we are about education, so you can learn to code and learn stem skills were mechamon. on top of that, we have robots starting to get out and the next phase for robotics, especially consumer robotics, which will be a big part of that, robots that can go to our houses and help us. some of your be smart devices, they can speak you are not questions of you. the next age is for you to be able to say, get me there and will get it for you. can you tell them a bit about your story? you have an interesting background. yes, thatis have an interesting background. yes, that is a photo of me from nigeria. i was born in nigeria, lifted uk when i was about 11 or 12, but before that i had been interested in science, engineering, stem. so when i moved to the uk, to cut a long story short, i went to university to study robotics and in that time i saw that when you combine consumer robotics with gaming, it gets a

really powerful engagement. it is a lot more interesting, as you can see. these robots are a bit late videogame characters in real life. they get better and stronger all time. that was the inception of the idea behind mechamon. how do you get the motion so realistic? there are two ways we do that. one is to be something called kinematics, where the robot is actually figuring out where it is moving too, and the second is that we have an amazing talented team of animators who work on it digitally and try to make that motion as realistic as possible. so what you are looking at here is years of lots of research and to behaviour and motion that is translating into the real world. finally, it is the mechanical engineering aspect. we have some proprietary technology that allows the robots to move like this. great. thank you there much. a man who wa nts to ta ke thank you there much. a man who wants to take over the world, but before we go, because we have this amazing routine taking place, we didn't want just you lot to see it, said earlier today they had a little activity outside the bbc building. take a look at this. music plays.

give it up one more time for silas and the mechamon robots. hands up if you own a phone. hands up if you have a phone with you. ok, keep your hands up if you have a camera on the phone. yes, pretty much everyone of course. i would say the average phone photo has about eight or ten 01’ phone photo has about eight or ten or 12 million pixels in it. so it is about a 12 megapixel camera. but, what would happen if you had more megapixels in your image. well, maybe you could do this. and it could zoom in, this is new york we

are looking at, and you can zoom in, and you can zoom in. this is an image with a million or so pixels, not with a million or so pixels but a billion. it was created by a device called a gigacam, which takes lots of zoomed in shops like this in stitches them together. it is one massive image of a billion pixels. but what would you do if you have a device that could take a billion pixel image in one go. well, obviously you would put it in space. and that is what our next guests have done. from the institute of astronomy at the university of cambridge, please welcome doctor georgia bohl sir and doctor anna harrison. this is the guy a satellite currently in space. this is a model of it. it is a space telescope. it is one of the cornerstone missions of the space agency. the real one is

ten times bigger. what have you been trying to find out using edge? we trying to find out using edge? we try to find out the shape of our galaxy and how it reformed. we need it to pinpoint exactly where the stars are where the structures are. for example how many spiral arms there are in the galaxy. are dropping him we knew that the milky way was a spiral with two arms. but what you are saying is that we only think we know —— i grew up thinking. what sort of things is gaia measuring? gaia is repeatedly scanning the sky and taking images at different times. by processing these images with a very competent at software system we can figure out how far away the stars are and how they move and with that we build up a map of the sky. it is basically like google maps for the galaxy. you have made some remarkable discoveries already, haven't you? yes. one thing we recently discovered is the milky way was

involved in a head—on collision with another galaxy early in its lifetime, about 10 billion years ago. we see that the stars are on these and long dated kind of sausage shaped orbits that show they have come from another galaxy. for that reason, the galaxy that crashed into us is named the sausage galaxy. please thank georgia and anna. that was fascinating. and what show is complete without a cheeky selfie? if you were there, see if you can spot yourself here. three, two, one, here we go. soi so i have a background in technology and magic. and magicians are interesting. there are allusions

accomplish what technology cannot. but what happens when the technology of the day seems almost magical? what happens when you can do this? now, 100 years ago that would have been the magic of levitation. is it possible to create illusions in a world where technology makes anything possible? jump. if you know how the trick is done, where is the illusion? but still, our imagination is more powerful than our reasoning.

and it is easy to a tribute personality to machines will stop these are quad copters. but they are more than mechanical flying machines. they analyse the environment around them and react to everything i do. advanced algorithms allow these autonomous machines to fly in close formation, aware of each other, aware of me. mathematics that can be mistaken for intelligence. and intelligence for personality. anthropomorphism, that's the illusion. an illusion created by technology and embroidered by our imagination to become an intelligent flying robot, a machine that appears to be a live. —— alive.

i think they say hello. hey, guys. that's it. all right. time to go home. come on, everybody. right over here. there you go. everybody, come on. you can fit in there. go on. there you go. everybody, no pushing, no pushing over there. everybody, there you go. you said you were a magician as well asa you said you were a magician as well as a technologist. how much of that was an illusion? there was a little bit of trickery involved. they are not really following my gestures or make a man's. they are preprogrammed. and the way they work is to have tiny little cameras inside them and they track that pattern on this magic carpet we see around the stage. magic carpet! that

is how they self localiser nowhere to go. a big thank you to marco tempest. thank you. thank you. applause. after almost seven months and 350 million miles, nasser‘s insight finally entered the martian atmosphere in november this year. what followed was seven minutes of terror before touchdown —— nasa. it is only the eighth time that nasa has successfully landed on the surface of mars and follows on the footsteps of rovers like opportunity and curiosity. rumours that have changed our perception and knowledge of the red planet of the past 15 yea rs of the red planet of the past 15 years —— rovers. and we were lucky enough to have a member of nasa's jet propulsion lab with us to speak on all things martian. what are the that course of time that wasn't apparent when first landed? we have

learned that there was a loss more water than we originally thought and it is much closer to the surface than we had thought. if we were to send humans there at some point we would be able to extract that water, turnit would be able to extract that water, turn it into energy, drink or bore water, and establish a habitat. so finding the water was a huge moment. what are the exciting moments have you had more recently? the most recent discovery on the curiosity mission was the discovery of ancient organics. it means we discovered methane like products which means it could have potentially have been hospitable for life in ——on mars at some point in the distant past and maybe someone in not so distant future. nasa has also been having to educate people about its work on mars, using the virtual augmented reality. i am going to turn on the ad. select all the mars mission is —— apa macro. get all the good feel

about what it looks like. take a selfie with it. a great time learning about. some of the details we are looking at, what are the parts and it they go wrong, you can't send it to fix it? if it brea ks we can't send it to fix it? if it breaks we cannot send a repayment. we have to make sure everything is triple redundant. absolutely fascinating stuff. victor, thank you very much. ai. that is what the future is about, if you believe the hype. computer programmes that learn from past experience, that improve, and that sometimes went to solve problems in ways that even we hadn't thought of. it is learning to drive, to play games, it has learnt to paint, it has learnt to understand what we say. and it is certainly true that al is already replacing us in particularjobs. now, for many

that thought is quite a scary prospect. not for saturn dougall, who runs a company that uses ai prospect. not for saturn dougall, who runs a company that uses al to help design apps. we have created a platform that allows anyone to create software. when you think about the hundreds of thousands of applications out there, they have common building blocks. how many people have an ad that uses facebook? how many people have more than one? and yet when you are building software people are rebuilding the same thing again and again. but that does not make sense, why did we do it like ours where we have these common building blocks, you can use them again and again, and it means we can build it faster, cheaper, and better. you want anyone to be able to build eight app, even if they can't code. if you think about the fact that everyone industry must have had an idea. 90% of people who have an idea to even go past the stage of an idea,

because it seems overwhelming. we are so much cheaper and so much faster because we are just using the code wonsan machines are basically finding where this has been done before, pulling it out of a lycra, putting it together, going to 32,000 people around the world, seeing who is available, using people for an hour a day or is available, using people for an houra day ora is available, using people for an hour a day or a week and putting together —— library. hour a day or a week and putting together -- library. we talk about somejobs possibly being replaced by ai, buti somejobs possibly being replaced by ai, but i imagine there are computer programmers in here and students who would like to be computer programmers for the next 20 or 30 yea rs, programmers for the next 20 or 30 years, and! programmers for the next 20 or 30 years, and i guess they thought they we re years, and i guess they thought they were safe from the ai revolution, but what we are saying here is that even those jobs are not safe from ai? and, again, ithink it is nuance. so what you think students should be studying at college now, are they studying the right things or those things going to be replaced? if i'm slightly controversial i would say the whole idea of stem and learning to code becoming an overarching thing and everybody becoming a developer, i

think that is so oversold. why do you need to be able to be in the digital economy, build ideas, build software, why do you need to build —— know how to code? you need to think about products, problems that need to be solved, whether it is at a micro level or a macro level. that isa a micro level or a macro level. that is a much more important. sachin duggal, everyone. thank you so much. thank you. and a click light show would not be a click live show without some lasers and lots and lots of applause —— click live. three, two, one, go. being chucked off stage. a fitting end. all that remains is to thank everyone who turned up to see a live and, you, at for watching. goodbye!

—— at home. hello there. here comes your weather forecast for the rest of this year and i have to say, for many of us, it doesn't bring any huge changes. it's going to stay pretty mild through the next few days. mostly dry as well although northern parts of the uk are going to see some bursts of rain and some brisk winds at times as well and that's certainly the case during saturday. this little area of low pressure moving across northern scotland. providing wet weather through the first part of the day. some windy weather too and the wind for all of us coming from the south—west, bringing this mild air in our direction. so we start off saturday morning with outbreaks of rain in parts of scotland but the worst of it looks likely to have cleared away by the time it gets light. still a few hefty showers through the morning and also some gusty winds. the black arrows here show wind gusts in excess of 40mp, might get close to 50mph on high ground but northern ireland

and england, perhaps the north midlands and wales will see some extra cloud, maybe the old spot of brain around. but the south, mainly dry and rather cloudy and murky to the day and as we had deeper into saturday, many areas will brighten up, particularly across scotland, sunshine across northern ireland and northern england and perhaps the midlands later in the day. should brighten up nicely. further south, or more in the way of cloud and we keep that mild feel in the south, temperatures coming down as the weather gets on in the norther half of the uk. we move out of saturday to sunday and we do it all again. we bring more wind across northern areas of scotland and england, much of it clear by the end of the night, the further south you go mostly dry. mild air returning once again from the south—west. sunday looks like this, some patchy rain. it'll mostly clear, but could linger for a good part of the day across the northern isles and largely dry, a lot of cloud in the west. best of brightness for nothern scotland, north—east england. those temperature is still pretty impressive for this time of year. into the last day of the year, monday, new year's eve, it's looking like another largely dry day. areas of cloud, mist and fog and patchy rain at times. again, those temperatures in double digits. if you're out celebrating in the evening, this

is the weather set—up. high pressure in charge, a weak frontal system in the north, so patchy rain and here we have the high pressure, still a lot of cloud trapped underneath it stood midnight, i'm expecting it should be dry but rather cloudy and a bit murky as well. welcome to bbc news, broadcasting to viewers in north america and around the globe. our top stories: president trump threatens to close the us—mexico border unless congress agrees to fund his wall. a roadside bomb has killed four people and injured 12 others on a tourist bus near the giza pyramids in egypt. the rising number of migrants trying to cross the english channel is declared a ‘major incident‘ by the british home secretary. satellite images reveal anak krakatau has lost over two thirds of its height and volume since it exploded last week killing more than 400 people. and monty python's michael palin and model twiggy are among the stars recognised in the new year's honours list.
